Why would anyone controlling such an aircraft deliberately take it to a hovering position above 100 feet of people who have never seen it before? Aren't these flight tests supposed to happen away from public's view? It looks as if on one hand, the government wants to keep a tight lid on these things, on the other hand, they want to give it all away so easily (based on stories such as yours), which makes no sense. I will be a skeptic until the day I can get to lick the surface of such a craft.
